[PowerPC] Fix the bug of ISD::ADDE to set its second return type to glue

Browse Source 
Summary:
This patch is to fix the bug imported by rL341634.
In above submit , the the return type of ISD::ADDE is 
14224: SDVTList VTs = DAG.getVTList(MVT::i64, MVT::i64), 
but in fact, the second return type of ISD::ADDE should be 
MVT::Glue not MVT::i64.
